The invention provides a compound of the general formula
wherein X is an oxygen or sulfur atom or a vinylene group, each of ℓ and m is an integer of 1 to 4, n is 0 or 1, the heterocycle comprising the nitrogen atom, the two alkylene chains and X is 5- or 7-membered, the two alkylene chains each may be branched, Y1 is a halogen atom, Y2 is a hydrogen or halogen atom, R is an alkyl group, which may be interrupted by one or more oxygen atoms, or an optionally halo-substituted alkenyl or alkynyl group and Z is an oxygen or sulfur atom. The invention also provides herbicidal compositions containing (thiono)carbamates of the above formula as active ingredient and a method of controlling weeds using these (thiono)carbamates. The phenyl (thiono) carbamates are capable of effectively controlling broad-leaved annual weeds and annual weeds belonging to the families Gramineae and Cyperaceae such as wild Echinochloa species, monochoria, toothcup and umbrella plant. The (thiono)carbamates are substantially nonphytotoxic to useful crop plants such as the paddy rice plant.
本发明提供了通式如下的化合物
其中X是氧原子、硫原子或乙烯基,ℓ和m各为1~4的整数,n为0或1,由氮原子、两条亚烷基链和X组成的杂环为5或7元,两条亚烷基链可以是支链、Y1 是卤素原子,Y2 是氢原子或卤素原子,R 是烷基,可被一个或多个氧原子或任选卤代的烯基或炔基打断,Z 是氧原子或硫原子。本发明还提供了含有上式(硫代)氨基甲酸酯作为活性成分的除草组合物,以及使用这些(硫代)氨基甲酸酯控制杂草的方法。苯基(硫代)氨基甲酸酯类化合物能有效防除一年生阔叶杂草和禾本科、莎草科一年生杂草,如野生越橘、单子叶、齿颊草和伞形科杂草。(硫代)氨基甲酸酯对水稻等有用的作物植物基本无植物毒性。
